How to program a discrete input parameter with a number

Table 3-6 shows how to connect Setpoint #2, an analog parameter, to a number. You can also connect a discrete parameter to a number. A discrete parameter, such as an alarm’s input source, can be connected to any discrete parameter type in Table 3-7, or it can be programmed with a 0 to signify the off state or with a 1 to signify the on state. Enter a value of 1 or 0. For example, if you program an alarm’s input source (Figure 3-7) with a value of 1, the alarm’s output (AL1 OS) will always be on.

To program a discrete parameter with a 1 or 0, perform the following procedure. The procedure uses Alarm1’s Input source as the parameter being programmed.
